Spring Boot is a framework that simplifies the development of Java-based applications, particularly those built with the Spring Framework. It provides a streamlined, opinionated approach to building Spring applications by eliminating the need for extensive configuration and boilerplate code.
With features like embedded servers, automatic configuration, and a wide range of starter templates, Spring Boot allows developers to quickly create stand-alone, production-ready applications.
Its focus on convention over configuration and its ability to integrate seamlessly with various databases, messaging systems, and web technologies make it a popular choice for microservices architecture and modern Java application development.
